ABSTRACT:
A hold-open door clip can be disengaged with simple outward pressure on the door. A counterweight body section causes the clip to assume a position substantially perpendicular to the piston rod when in its free hanging position. The end of the piston housing will engage a tang that extends from the top edge of a first body section and will slide the hold-open clip freely along the piston rod.
